InteloI already `sudo umount /dev/mapper/sdb3` but `sudo fsck.ext4 -pf /dev/mapper/sdb3`  says /dev/mapper/sdb3 is in use. Any clues? its an open luks encrypted partition. Does not shows in `df` or `/proc/mount`. If I reboot, open luks partition again, it will automound and open in thunar. then I will umount and land to same situation00:11
Bashing-omcross post: Intelo "Try to identify: ' sudo fuser -m /dev/mapper/sdb3 ; ps auxw | grep <that PID> ' ."00:14
oerheksjsut wait for fsck to finish00:14
oerheksmaybe it will never..00:14
sarnoldthe "filesystem is in use" thing prevents fsck from starting00:14

oerheksi hope you have a backup of your precious data :-D00:15
sarnoldbecause filesystem implementations in the kernel are extremely brittle; if you change the disk while the device is mounted, you can do *anything* to the computer00:16

lorenzohi. i need help with a thing, please.00:17
lorenzoi'm using teamspeak 3, and i have "push to talk" option00:17
InteloI had drive sdb.  sdb3 was encrypted parition. I luks open i to . it shoudl be now /dev/mapper/sdb3. but it mounted the real os  to /dev/vgxubuntu/root00:17
lorenzowhen i have my click on teamspeak, it's working. when i have my click (mouse) on desktop, isn't working00:17
Intelosolved but i wonder00:17
oerhekslorenzo, so teamspeak prop software wants you to keep focus?00:18
InteloIs fsck.ext4 -c best for deep scan?00:18
lorenzooerheks, yes. i just want to use teamspeak in background00:19
lorenzowhen teamspeak is in background, i can't use my microphone00:19
lorenzoi'm new on linux and  I think i need to run teamspeak with "run administrator"00:21

sarnoldyou almost certainly don't need to do that; I've never used teamspeak but it doesn't feel like the sort of software that would require admin privs -- it doesn't even feel like it'd work well, since running GUI programs as other users is usually pretty difficult00:22

Oski146hello can i know when kernel 5.20 with amd support is coming? i still cant await it that the support gets wider00:29
murmelOski146: wrong channel for that. and 6.0 will be probably released this sunday or next.00:30
Oski146which cannel can i go00:31
Oski146channel*00:31
sarnoldOski146: kinetic will be released in a month with 5.19. probably the next ubuntu release in april will have a newer kernel. *maybe* there'll be a newer HWE kernel for jammy before then, but I'm not sure00:31
Oski146lk thsnkd for the explanation :)00:32
Oski146thanks*00:32
murmelsarnold: nah, 5.19 will come out when 22.04.2 gets released (which is around april?)00:32
murmeli mean released for 22.0400:32
Oski146oh that late?00:33
sarnoldmurmel: 5.19 is available in kinetic *today* https://launchpad.net/ubuntu/+source/linux00:33
InteloIs fsck.ext4 -c best for deep scan? how do I fix and scan in depth?00:33
sarnoldIntelo: best is to switch to zfs and then you can run online scrubs00:33
murmelsarnold: yes. I was talking jammy00:33
Intelosarnold oh whats online scrub?00:34
Intelosarnold and is zfs better than ext4?00:34
Oski146i heard 5.20 would have amd  ryzenfirmware support so i cant download the kernel 5.19. on arch and such is not supported yet. can you give me the channel name that i candiscuss on the right place?00:34
sarnoldIntelo: zfs can repair faults without taking the filesystem offline00:34
murmelOski146: maybe ##linux ?00:35
Oski146thanks00:35
oerheks5.19 gives zen support, it cripples performance with 50%++00:36
oerheksdue to retbleet00:36
Intelosarnold like it can repair on a mounted partition?00:37
oerhekssorry to tell you00:37
Intelosarnold and is zfs better than ext4?00:37
murmelIntelo: depends who you ask00:37
Intelowhat sarnold has to say?00:38
Intelomurmel which one is latest?00:38
sarnoldIntelo: It Depends :) I really prefer zfs for storing a lot of data; but ext4 is easier to use on a machine with only one disk00:38

enigma9o7there was a recent article showing startup memory usage with various ubuntu flavors, and ubuntu/gnome used twice as much memroy as lubuntu/lxqt.02:00
enigma9o7but then of course apps are all the same memory usage, and there's other things besides memory usage to consider02:01
enigma9o7if you are using an old pc (10+ years) gnome is noticably slower.  on a modern fast pc, you wouldnt even notice.02:01

Princess15Hi guys, I want to use a different cipher instead of aes to encrypt my Linux OS, how can I set my custom LUKs settings, I'd like to switch from aes to serpent or twofish for LUKS, how do I accomplish this?07:08
InteloFailed to load R0 module /usr/lib/virtualbox/VMMR0.r0: Unable to locate imported symbol 'SUPR0FpuBegin' for module 'VMMR0.r0'07:08
murmelPrincess15: you would need to setup the partitions yourself, and then during the installer, select manual and assign the correct paths to the partitions07:10
saltdshe will figure this out07:11
Princess15sBut07:13
Princess15So should I do a Linux OS install via COmmand line?07:13
Princess15Will this take 30 minutes of precise commands07:13
murmelPrincess15: you would need to create the luks containers in cli, but the rest you can do through gui07:14
Princess15So I create the luks container upon live usb boot up07:17
murmelPrincess15: first partitions, then containers07:17
Princess15hmmmm07:17
murmelPrincess15: is there a reason why you want to use serpent/twofish?07:26
Princess15I think aes is more likely to be decryptable due to increased research due to mass usage.07:27
Princess15Thus, a less popular cipher might not have enhanced decryption capabilities07:27
Princess15due to lack of study07:27
Princess15on the cipher07:28
murmelPrincess15: but you do realize, because aes is also more popular more eyes look at it to secure it better?07:30
Princess15yeah07:30
Princess15I realize that07:30
Princess15but AES is so much more used07:30
Princess15Its just a giant honeypot07:31
Princess15waiting for a decryption method07:31
Princess15I'd estimate, and Im sure you can find the data, that 80% of encrypted traffic is AES07:31
Princess15HTTPS, OPenVPN, etc07:31
Princess15of course theres camelia, wireguard now07:31
Princess15But just07:31
Princess15Majority is AES07:31
Princess15its a mega decryption target07:32
murmelPrincess15: please use enter less often07:32
murmelYes I get that. but at least with the disk encryption I have it in my hands, if aes would ever get broken, I can reinstall within half an hour (with a different enc)07:33
Princess15Yeahm thats what i want to do, install  another os07:34

Guest95does ubuntu come with command tools for zip and rar files? and if i need to install them, are these correct tools: rar, unrar, zip, unzip? and i install them like this: sudo apt-get install rar unrar ?14:35
wezGuest95: Correct on all counts, but why are you asking this question instead of just running the commands?14:36
rob0I bet you have at least zip/unzip by default.14:37
ravageGuest95, p7zip-full supports all of the above14:37
wezrob0: generally tar by default, depends on the packages installed14:38
Guest95thanks! i just want to be sure, so i don't spiral down the wrong rabbit hole14:39
wezGuest95: OK14:40
Guest95each of these will do only one file type? i mean unzip works on zip, and unrar works on rar? so i need to know which is which file type? thing is i am trying to untangle a big mess here with both zip and rar files in the same folder14:45
ravageit helps to read what has been written to you already14:46
rob0Typically zip and rar archives include the file type in the filename.14:48
rob0And shell globbing can easily distinguish them: "unrar *.rar", "unzip *.zip".14:49
rob0Note that those commands might be dangerous, as one archive could overwrite what another one contained.14:50
Guest95can i use p7zip to unrar or unzip a dozen files in one go? i want to extract all archives at once, each to its own folder, if possible.14:54
